We could also add an attribute prefix by which to request that the
mechanism implement a [POSIX thread] cancellation point around getting
an attribute, thus making it easier for callers to impose timeouts.

We could also have an attribute that imposes a particular timeout,
though that requires baking the timeout value into the attribute name,
and so that's a bit obnoxious.
